Dear editor,

Next year I'll go to university and becoming a college student, and I have never been away from my parents．I don't know what to face my university life．I hear many new students are at a loss when we are at university．They can't take care of themselves in everyday life, and often feel lonely and homesick．Clothes, money or mobile phone are sometimes gone．And because different weather and food, they often get ill．Some even rent rooms outside the campus, which I don't think it is so safely． Could you tell me how to deal with these problems so that I would be able to get used the university life in the future．
